Step 1: Preheat your oven to 325°F (163°C). Grease a 9-inch springform pan and set aside.
Step 2: In a mixing bowl, combine the graham cracker crumbs, melted butter, and cinnamon. Mix until the crumbs are evenly coated. Press the mixture firmly into the bottom and slightly up the sides of the prepared springform pan.
Step 3: Bake the crust in the preheated oven for 8-10 minutes. Remove and allow it to cool completely while preparing the cheesecake filling.
Step 4: In a large bowl, beat the softened cream cheese with an electric mixer until smooth and creamy. Add the granulated sugar and continue mixing until fully combined.
Step 5: Blend in the sour cream, eggs, vanilla extract, and cinnamon. Mix on low speed until the ingredients are well incorporated, being careful not to overbeat the batter. Pour the cheesecake filling over the cooled crust, spreading it evenly.
